Yes, you can usually still use water when your water heater is broken, but only cold water, and only if the tank itself is not actively leaking. In Aurora, once you spot water pooling under the tank, you should shut it down right away. Our water here is very hard, right around 11.2 grains per gallon, and that packs the bottom of a tank with mineral sediment that speeds up corrosion and brings on leaks faster than a lot of the country deals with.
Cold showers at this elevation are rough in the winter, and a broken heater is a real headache. It does not shut off your whole house, though. It just changes what that water is safe to do.
Let me walk you through it. If your heater simply stopped making hot water, your cold lines still work fine, so you can flush toilets, wash your hands with cold, and run the dishwasher on a cold cycle. What really matters is whether the tank is leaking. A tank that just quit heating is a comfort problem you can live with for a bit, but a leaking tank causes water damage, and running more water through it only feeds the leak. The cold-water shutoff valve sits at the top of the tank, and closing it stops fresh water from entering while still leaving the rest of your plumbing usable in most homes.
Conditions around here make all of this worse. Our expansive bentonite clay soil and hard freeze-thaw winters already stress the pipes feeding your heater, and then the mineral scale our water leaves behind builds up so the tank bottom takes a real beating. That scale traps heat against the steel, which weakens it and shortens the tank’s life, so a heater that might last 12 to 15 years elsewhere often gives you less here. When a tank leaks in Aurora, it is rarely a fluke, and usually the tank is just worn out.
How long will a water heater last once it starts leaking?
There is no set countdown once a tank starts leaking, and that is the frustrating part. It could hold for a few weeks or months, or it could fail suddenly, and what matters most is where the leak is coming from. If water is dripping from the drain valve or a loose connection at the top, that is often a repair, and the tank may have real life left in it. But if the water is seeping from the tank body itself, the steel has corroded through and no repair will hold, so that one gets replaced.
In Aurora, the tank-body leak is the common one, because our very hard water drops calcium and magnesium into the bottom of the tank where it bakes into a crust that eats through the steel from the inside. So when we scope a leaking heater here and the tank is the source, we tell people straight that they should plan on a replacement rather than a patch, since stretching it out just risks a flood.
How long can a water heater leak before it bursts?
You do not want to gamble on how long a water heater will leak before it bursts. A slow drip can carry on for days or weeks, but a small leak can turn into a full rupture with little warning, and a failed tank can dump 40 to 80 gallons of water into your home in minutes. That means a soaked basement and ruined drywall, not just a quick mop-up.
The risk climbs fast when you have high water pressure and a failing temperature-and-pressure relief valve working together. Many Aurora homes run on high municipal pressure, which is exactly why a pressure-reducing valve matters here and why the T&P valve on your heater is not optional. When pressure builds inside a corroded tank with no working release, that is when a leak becomes a burst. We treat any tank-body leak as a same-day problem rather than a wait-and-see, and Superior Mile High Plumbing offers 24/7 emergency service, because a leaking tank is one of the calls we would rather take at 2 a.m. than see flood by morning.
Can a broken water heater cause a high water bill?
Yes, and a broken water heater can hit both your water bill and your energy bill at once. When a tank leaks, hot water escapes and cold water flows right in to replace it, and then your heater fires up to warm that new cold water back to temperature, so it runs far longer than it should. You lose the water and the energy used to heat it.
A steady drip adds up faster than most people expect, and even a drip of one drop per second can waste thousands of gallons over a year. There is a second Aurora-specific culprit too, because our hard-water sediment settles at the tank bottom and acts like an insulating blanket over the burner or heating element, forcing it to run longer to push heat through the crud. That can spike energy use by a noticeable margin. So if your bill jumped and your usage did not, your water heater repair may be the first thing worth checking.
What should I do if my water heater breaks?
If your water heater breaks, move in order and put safety first. Here is what to do the moment you find a broken or leaking heater:
- Shut off the cold-water supply valve at the top of the tank to stop fresh water from feeding the leak.
- Cut the power. For an electric unit, flip the breaker. For a gas unit, turn the gas control to off.
- If the leak is heavy, drain the tank with a garden hose run to a floor drain or outside.
- Keep the area dry and move anything valuable off the floor nearby.
- Call a licensed plumber to diagnose repair versus replacement.
Do not run more hot water hoping to finish a shower, because that only pulls in more cold water and worsens the leak. One local homeowner shared in a Google review how our team responded to a failed water heater the same day with strong communication and even lined up a water mitigation company to limit the damage, and that kind of coordination can keep a bad day from turning into a disaster. If the tank is done, our water heater installation in Aurora gets your hot water back and brings the setup up to code. On a closed system, where a backflow preventer, check valve, or pressure-reducing valve sits upstream, Aurora code requires an expansion tank, and that is part of a proper install. You can see the full range of options on our water heater services page.
